METHOD OF BENDERING HIGH EOLS SQLW No Drawing. Application filed June 11, 1927, Serial no. means, and in sunn awe is, I Renewed June 8, 19321.

This invention relates to a method of renate alcohol is treated with a dispersion agent dering higher alcohols soluble. More parwhichis obtained as a product when sulticularly, the invention is concerned with phonatmg fats or fatty acids in the presence di solving alcohols comprising four onmore of concentrated aliphatic acids, acid anhycarbon ato ns, dr1des, or acid chlorides.

constitute the most prominent examples of fatty acide halides, and the invention is not restricted to the chlorides.

The following two examples may be given for the production of the reparations from e sulphonates recovered by sulphonatmg fats or oils in the presence of aliphatic aclds or acid anhydrides, (e. g. water-free butyric acid or acetic anhydride).

Example 1 25 parts of sulphonate (as per parts of water-insoluble butyl alcohol 65 parts of water I give a clear solution which may be employed in the manner statedabove.

Emample 2 60 parts'of sulphonate (as in Exam le 1) parts of water-insoluble amyl alco ol 5 parts of cyclo-hexanol give a clear solution which dissolves clearly in water, alkali solutions, and diluted acids of the concentration given in the specification.
